项目摘要

AbstractA non-technical description of the project, which explains the project's significance and importanceThe spectacular scenery of Grand Teton National Park is largely the result of movement along the Teton Fault, which is still active today. Numerous lake basins populate the mountain front and earthquakes resulting from fault movement produce landslides that accumulate distinctive sediment layers on the lake floor. This project will investigate these sediments in order to determine the characteristics of the layers resulting from fault movement and to calculate the recurrence interval of earthquakes in the Grand Teton region over the past 15,000 years. In addition to developing methods for the long-standing problem of identifying the tectonic influences upon sediment deposition, this research will help Grand Teton National Park evaluate earthquake hazards and provide the basis for an educational program for park visitors. A technical description of the projectThis EAGER project will employ a comprehensive suite of well-established methods to investigate this distinctive geologic setting, where past tectonic activity is unusually well preserved in lake sediments. Multi-beam sonar bathymetric mapping, seismic surveys, and sediment cores from multiple lakes located directly on the Teton fault will be evaluated to produce: i) a high-resolution (centimeter-scale) bathymetric map of lake-floor morphology; ii) an inventory of landslide deposits and slope failures preserved in multiple basins positioned along the Teton fault trace; and iii) a continuous and accurately dated 15,000-year-long record of earthquakes and earthquake-driven disturbances at Grand Teton National Park. The paleoseismic record generated through this research is a key initial step toward developing a solid understanding of interactions among tectonic, climatic, and geomorphic processes, including their relative roles in driving landscape evolution. The results will also contribute to the development of a promising method for constructing paleoseismic records from lake sediments.
对项目的非技术性描述,解释了项目的意义和重要性大提顿国家公园的壮观景色在很大程度上是沿着提顿断层运动的结果,该断层至今仍在活跃。山前分布着许多湖盆,断层运动引起的地震产生的滑坡在湖底堆积了独特的沉积层。该项目将调查这些沉积物,以确定断层运动产生的地层的特征,并计算过去15,000年来大提顿地区地震的重复间隔。除了为确定构造对泥沙沉积的影响这一长期存在的问题开发方法外,这项研究还将帮助大提顿国家公园评估地震危险性,并为公园游客的教育计划提供基础。该项目的技术描述这一迫切的项目将使用一整套成熟的方法来调查这一独特的地质环境,在那里,过去的构造活动在湖泊沉积物中保存得异常完好。将对直接位于蒂顿断层上的多个湖泊的多波束声纳测深图、地震勘测和沉积物岩心进行评估,以产生:i)高分辨率(厘米级)湖底地貌等深图;ii)沿蒂顿断层轨迹的多个盆地中保存的滑坡沉积和斜坡断层清单;iii)大蒂顿国家公园15,000年来地震和地震干扰的连续和准确日期记录。通过这项研究产生的古地震记录是深入了解构造、气候和地貌过程之间的相互作用,包括它们在驱动景观演变中的相对作用方面迈出的关键的第一步。这一结果还将有助于开发一种从湖泊沉积物中构建古地震记录的有前景的方法。
